I was watching the Frys.com Open (Soon to be Safeway?) yesterday and when Kevin N. hit his Titleist driver off the deck the sparks went flying. It was so impressive that during the telecast it was repeated in slow motion.
Do we know what's causing this impressive phenomenon? Is it only the 915 drivers or does it to the other "metals".
I don't recall having this discussion with the 913s.
Anyway, I think its great for Titleist. Dive a ball and watch the sparks fly.
